I want to measure coverage of packages in src/app by tests in src/test. And currently generating coverage profile by running custom script that runs coverage for each package in app and then merges all coverage profiles into one file. Recently I heard that in go1.10 we are able to generate coverage for multiple packages.
So I tried to replace that script with oneliner, and tried running
GOPATH=${PROJECT_DIR}:${PROJECT_DIR}/vendor go test -covermode count -coverprofile cover.out -coverpkg all ./src/test/...
It gives me "ok test 0.475s coverage: 0.0% of statements in all"
When I do
cd src/test/
GOPATH=${PROJECT_DIR}:${PROJECT_DIR}/vendor go test -covermode count -coverprofile cover.out -coverpkg all
Logs show that specs are runned and tests are successfull, but still I have "coverage: 0.0% of statements in all" and empty cover.out.
What am I missing to properly compute coverage of packages in app by tests in test?
